Using a touch screen phone to read novels for a long time may cause a certain degree of damage to the eyes. Because the brightness, contrast, and color of the screen are very high, it will cause strong stimulation to the retina. Prolonged contact with this stimulation may cause eye fatigue, dryness, vision loss, and other problems. In addition, the screen of a mobile phone was usually larger than the screen of a book. It was more likely to distract people's attention, resulting in a lack of depth when reading. It also caused a certain amount of pressure on the eyes. In order to reduce this damage, the following measures are recommended: 1. Control the time of use: Try to reduce the time of using the phone to read novels, especially when it is a long-term outdoor activity or when you need to concentrate for a long time. 2, adjust the screen brightness: adjust the screen brightness to an appropriate level. Don't adjust the screen brightness too high to reduce eye irritation. 3, adjust the screen contrast: adjust the screen contrast to an appropriate level. Don't adjust the screen contrast too high to reduce eye irritation. 4 Control the brightness and contrast of the screen: When reading, reduce the brightness and contrast of the screen to reduce the pressure on the eyes. 5. Increase reading distance: Maintain an appropriate distance to reduce short-distance stimulation to the eyes. 6. Rest often: When reading, you should rest your eyes every once in a while. You can do eye exercises or take a break from afar.
